SPECIFICATION forming part of Letters Patent No. 513,862, dated January 30, 1894.

Application led September 19, 1893. Serial No.485,816. (No model.)

T all' whom, it may concern.-

Beit known that'LWILLIAM I-l. BARRETT, of Weir, in the county of Cherokee and State of Kansas, have invented a new and Improved Dumping Apparatus, of which the following is a full, clear, and'exact description.

My invention relates to improvements in that class of apparatus which is used for dumping cars, and especially for dumping coal cars after they have been raised in an elevator cage.

The object of my inventionis to produce an extremely simple, strong and rapidly operating apparatus of this kind,which is adapted to Work in connection with an ordinary car, and which when the car is raised to the required heightv will'automatically dump the load into an adjacent chute.

To these'ends, my invention consists of certain features of construction` and combinations of parts, which will be hereinafter described and claimed.

Referenceis to be hadto the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a sectional elevation of the apparatus embodying my invention, showing the car in position to dump its load. Fig. 2 is a sectional plan of the same; and Fig. 3 is a cross section on the line 3-3 of Fig. 2.

The elevator cage 10 is o f substantially the usual kind, comprising the top and bottom frames 11 and the connecting posts 12. The

cage is arranged to move vertically in the well 13, which isformed between the timbers in substantially the usual way,and on opposite sides of the well are the usual guide posts 14, which are clasped by plates 15 and lugs 16 on the elevator cage, so that the latter moves steadily. The cage is operated by cables 17 in the usual way, and the entire construction above described is of substantially the usual kind, and may be varied in the ordinary ways without affecting the" principle of myinvention. The cage 10 carries a dumping platform 18, which is mounted on tilting frames 19, these being secured'to opposite sides of the platform, and at their lower ends the frames are journaled on a shaft 20, which is mounted in suitable supports on the bottom of the cage l0.

On the tilting platform 18 are tracks 2l on which the car 22 may run. The car is like the ordinary dumping car, with the exceptionJ of its end gates, and after it has been run upon the tracks 2l it is held in position by swingin g clamps 23, which are arranged on opposite sides of the dumping platform 18, and which arev provided with oppositely extending arms 24E.v and 25 adapted to engage the lianges of the car wheels and also to press against the faces of the wheels, and the car is thus held from moving either l'aterallyor longitudinally. The clamps 23 are fulcrumed-on the sides of the platform, as shown at 26, and the lower ends of theclamps project below the fulcrums and are pivoted to connecting rods 27, which extend inward beneath the car and are connected by ordinary eccentric straps with the eccentric 28 on the shaft 29, which shaft is journaled in suitable bearings beneath the platform 18 and extends in a line parallel with the car. The shaft 29 has at its ends levers or arms 30, which project upward above the platform, and by swinging the arms or levers 30 laterally, the eccentricy and rods may be operated so as to swing the clamps 23 inward or outward as desired. The eccentrics are arranged to operate in opposite directions so that the clamps will move simultaneously inward or outward, this being necessary, as the clamps are on opposite sides of the car.

The dumping of the car is effected by means of guides 31 which are arranged on.

opposite sides of the elevator well, and are held rigidly in place,these guides being curved outward as shown in Fig. 1, toward the chute 32, into which the load of the car is to be dumped, and the curves in the guides are arclearly in Fig. 1. The guides 31 are clasped by shoes 32a on opposite sides of the tilting platform 18, and these shoes are secured to the ends of a shaft 32b which is journaled on the platform, and which by turning, permits the shoesrto follow the guides 31. When the car and the tilting platform are in a horizontal position, the rear end of the car rests on posts 33 on the cage and the load is placed a little behind the center of gravity so as to keep the car level. As the cage 10 is lifted, however, the shoes 32EL follow the curves of the guides 31 and cause. the platform and car .9o ranged directly opposite the chute, as shown IOO to pull forward so that the load is dumped into the chute 32.

The car is provided at one end with a swinging end gate 34, and both ends may be thus provided if desired. This end gate has at its upper edge and on opposite sides, arms 35, which are journaled on the sides of the car, and the gate is also provided with a hook 36 which engages a chain 37 suspended from the top of the cage 10, and when the car is in a horizontal position, the chain is of sulicient length to permit the end gate to drop and close the end of the car, but when the car is dumped, its forward end of course drops, while the chain holds up the end gate, as shown in Fig. 1, and the load slides freely from the car into the chute.

The chute 32 is provided with a gate 38, carried on the lower end of a rod 39, which is piv oted` to the outer end of a lever 40, this being fulcrumed on a suitable support, as shown at 41,and which extends overa bar 42, thus limiting the downward movement of the inner end'ofthelever. The leveris provided at its inner end with a weight 43,. which isof suflicient heft to raise the gate 3S, and the inner end of the lever extends into the elevator well So as, to be struck bythe cage lOwhen the latter isl raised. This arrangement causes the gate 38 to close the chute 32 at the same time that the car is dumped, and the load is retained in thechnteuntil the car starts downward, when the weight 4,3 drops and raisesthe gate so as to' p ernlit the load to slide into the screens or other place in which it is deposited.

Having thus described my invention, I claim as new and desireto secure by Letters Patentl. Adnm-pingapparatns, comprisingan ele- A vator well or shaft, two curved guides-one on each side of the said well, a cage having guided movement in the well, a tilting platform on the cage, a transverse shaft jonrnaled on the platform,and shoes secured to the ends of the shaft, said shoes being recessed to clasp the said guides, substantially as described.

2. In a dumping apparatus, the combinai tion of the cage, a tilting platform on the cage,

a car mounted on the platform and provided with a swinging end gate, and means, as a hook and chain, for connecting the end gate with the cage top, substantially as specified.

tically movable cage, a dumping mechanism thereon, a chute located laterally ofthe path of travel of the cage, a gate in the chute, a movable part held in the path of travel of the cage, and an operativev connection between the said part and the gatesubstantially as specified.

5. In a dumping apparatus, the` combination of thejvertically movable cage, the dumping mechanism thereon,the chute at one side of the path of thecage, the gatel in the chute, and the Weightedlever having one end connected with the gate and the other end extending into the path of thecage, substantially as specified.
